Describe the electro-chemical series and its significance

Electro-chemical Series:

• The electro-chemical series is a list of electrodes and their standard electrode potentials arranged in order of decreasing oxidizing power. 
• The oxidizing power of an electrode is defined as its tendency to oxidize other species in a redox reaction.
• The electro-chemical series is significant because it can be used to predict the direction of electron flow in an electrochemical cell
• An electrode with a higher standard electrode potential will act as an oxidizing agent, while an electrode with a lower standard electrode potential will act as a reducing agent.
